DAMPER REGULATOR.

To all whom it may concern.-

'Be it known that I, DOCTOR FRANKLIN MORGAN, a citizen of the UnitedStates, re.

siding at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Damper-Regulators, ofwhich the following, when taken in connection with the drawingsaccompanying and forming a part'hereof, is a full and complete.description, sufiicient to enable those skilled in the art to which-itpertains to understand, make, and use the same.

The object of this invention is to obtain an apparatus by means of whicha determined variation in temperature of a confinedbody of air willproduce movement of a'piston or connecting rod, and thereby performdesired work, while at the same time means are provided sojthat if anyconsiderable quantity of such air escapes from the confining vessel whenthe temperature thereofis raised and the pressure :thereof is aboveatmospheric pressure additional air will be automatically supplied tosuch vessel when the same is at atmospheric temperature, therebyinsuring continuous and uniform operation of the apparatus. i

A further object of this invention is to obtain an apparatus ofwhich theoperation will be uniform.

Figure 1 of the drawings referred to as forming a part of thisspecification illustrates an apparatus embodying this invention invertical sectional view with an elevation of the front of a heatingapparatusand with a plied to such cylinder when required while thecylinder and contents are in a cooled condition.

A is a cylinder closed at the upper end by the head a and at the lowerend by a movable wall in base B. Base B consists of the parts I) b. C isa diaphragm forming a movable wall secured in place between such partsI) b.

Parts I) b are respectively provided with apertures therein. Suchaperture in part b Specification of Letters Patent. Application fi ledApril 27,1905. Serial 1%. 257,749.-

which water or other liquid.(lettered F) may flow from cylinder A intothe space between l) b of the'head Band phragm C. v v

F is a lever pivotally mounted on fulcrum f. I v

G is a connection'between leverF and the under side of diaphragm C.

in contact with 'dia g is a pin in connection G, against the under 1sideof which the lever F is held by weight H. Weight H is adjustable onthe lever F.

I is a pipe connected, by means ofpipe J, to 5 the steam-supply of theheating system in which'this apparatusis placed, and K is asteam-discharge pipe connected to the lower end of pipe I.

L is an ordinary venting-valve attached to pipe Kby pipe Z andpermitting air to flow therethrough from pipe K, while preventing waterof condensation or steam to any con-. siderabl'e amount flowingtherethrough M is the discharge-pipeofventing-valve L.

' Whenthe apparatus embodying this invention 1s attached to asteam-heatingdevice wherein an exhaust-pump is used, the

of such pump, while in other vacuum steamhe ating systems such pipe mmaybe connected to the aireduction pipe.

N is aclosed cup arranged to hold merpipe M may be attached to -,theexhaust side cury or other liquid, and O is apipe establishingcommunication between the cup N and the interior of cylinder A. y

P is a vertical pipe communicating with the cup atit's lower endand openinto the cup Q at its upper end. Cup Q is open to the atmosphere. a a

R is a flexible cord attached .to lever F at one end and extending fromthence over the pulleys S Sand attached at its other end to damper T ofthe steam-generator U, as at t.

The apparatus is shown in the drawin s with the air which constitutesthe expansib e member operating the device and which is contained incylinder A expanded so that the damper is closed. At such time theexpansion of the air forces the liquid E against diaphragm C and alsoforces the mercury containedin cup N into pipe P until a sufficientuantity of such mercury is in such pipe P (as to balance the pressure incylinder A. If

the pressure in cylinder A is suflicient, all the mercury in cup N maybe contained in pipe P and cup Q, and any additional pressure incylinder A will force some of the heated air therein underneath themercury in pipe P, whereupon such air will rise through the mercury andescape to the atmosphere.

When the contents of the cylinder A are cooled and the pressure in suchcylinder thereby reduced, mercury in pipe P will flow into cup Ntherefrom, and in case any heated air from the'cylinder hasescapedthrough ipe P, as above described, additionalair will W into thecylinder A to replenish such cylinder. I

The air constituting the expansible member ofthis apparatus in cylinderA is warmed by steam or water of condensation flowing through pipe I. Incase air is contained in pipe 1 when steam or water of condensationenterssuch pipe through pipe J such air will flow into pipe I throughventing-valve L and into pipe M.- The venting-valve L is supplied toprevent the trapping of air in pipe I, as might occur if the end of pipeK were closed by water of condensation.

Liquid Eis used to prevent the heated air -.of cylinder A coming .in'contact with diaphragm C.

In the operation of this apparatus steam in pipe I heats the airin-cylinder A. When the heated air forming the expansible member in.cylinder A cools, as by the cooling of the contents of pipe I and theradiation of heat from cylinder A, such air contracts, the pressurethereof on liquid E is thereby lessened, and theweight H on lever F willturn such lever on fulcrum f to raise connection G and diaphragm C andalso to raise damper T of steam-generator U.

.= The pipe P is of suflicient height to hold a column of liquidrequiring a pressure to sustain it equal to the pressure desired incylinderA when the air therein is heated. Hence when water issubstituted for mercury V as the liquid'therein (as it may be) the pipeP must be at least, say, thirteen and six-tenths times as long as it iswhen mercury is used, and cup N must be proportionately large.

- Havingthus described. my invention, what I claim as new, and desire tosecure by Let- .terfs Patent, is

L 1; A=receptacle provided with a movable wall, means to automaticallylimit pressure of heated an in the receptacle, and to automatlcallyreplenish, when the an 111 the receptacle is cooled, air forced from thereceptacle when heated, means to raise the temperature of the air in thereceptacle to above climatic temperature, a damper, a fulcrumed lever, aconnection between the lever and the damper and a connection between thelever and the movable wall and nieans to vary the pressure of theconnection against such movable wall.

2. A receptacle provided with a movable wall, means to limit pressure ofheated air in the receptacle, and to automatically replenish, when theair in the receptacle is cooled, air forced from the receptacle whenheated, a pipe to convey heating fluid, such pipe extending through thewall of. tho'casing thereinto and therefrom and means to vent such pipeof the air contained therein, a fulcrumed lever, a connection betweenthe lever and the movable wall, and means to vary the pressure of suchconnection against the movable wall.
